Starcloud builds megawatt-scale data centers in low Earth orbit and leases GPU compute, storage, and data processing capacity to customers. Satellites carry large GPU clusters and storage, with power from onboard solar panels and cooling in vacuum; customers access resources over the network and pay by usage. Unlike terrestrial cloud providers, Starcloud avoids land, water, and permitting bottlenecks by operating in orbit, and benefits from space-based energy and cooling to reduce costs and emissions. Its goal is to extend digital compute beyond Earth’s surface, enabling scalable, sustainable AI workloads through orbital data centers.

Simplify's Take
What believers are saying
- Raised $170M Series A at $1.1B valuation in March 2026, fastest YC unicorn.
- Starcloud-2 launches October 2026 with GPU clusters, generating cash exceeding costs.
- Delivers 10x lower energy costs via 24/7 solar and radiative cooling.
What critics are saying
- FCC denied 88,000-satellite proposal February 2026 over orbital congestion.
- SpaceX undercuts GPU leasing by 50% using Starlink's 6,000+ satellites.
- Radiation degrades NVIDIA H100s by 50-70%, halting Starcloud-2 by 2027.
What makes Starcloud unique
- Starcloud deploys NVIDIA H100 GPUs on 60-kg Starcloud-1 satellite, first orbital GPU compute.
- Founders from SpaceX, Microsoft, Airbus enable megawatt-scale orbital data centers.
- Leases GPU hours to satellites like Capella Space, avoiding Earth downlink bottlenecks.

↓ -14%Orbital, a startup building space-based AI data centres, has raised an undisclosed amount in funding led by Andreessen Horowitz's a16z Speedrun. The company plans to launch its first test mission, Orbital-1, in April 2027 to demonstrate proof-of-concept for orbital AI infrastructure. Orbital aims to address AI's energy crisis by deploying satellites in sun-synchronous orbits 1,200 miles above Earth, running entirely on continuous solar power whilst using radiative cooling to dissipate heat. Each satellite will house Nvidia-powered GPU clusters designed for AI inference workloads, with latency comparable to terrestrial fibre connections at 20 to 40 milliseconds. The company is opening Factory-1, a research facility in Los Angeles, to manufacture its compute satellites. Rather than attempting repairs in orbit, Orbital will replace satellites at end-of-life with controlled deorbit and burn-up on reentry.
Orbital compute infrastructure startup Starcloud has raised $170 million at a $1.1 billion valuation, as companies including Elon Musk's SpaceX and Jeff Bezos' Blue Origin race to move power-hungry AI data centers off-planet.
Starcloud has raised $170 million to develop its next-generation spacecraft, achieving a valuation of $1.1 billion and unicorn status. The funding will accelerate the company's plans to deploy an 88,000-strong orbital data centre network, pending regulatory approval.
Starcloud, a "data center in space" firm, has secured investment from In-Q-Tel, a venture firm funded by the CIA. This partnership aims to accelerate Starcloud's development of orbital data centers, offering high-performance AI compute capabilities for satellites. Founded as Lumen Orbit, Starcloud plans to deploy LEO satellites using 24/7 solar power. The company has raised over $20 million, with investors like Y Combinator and Sequoia. The investment size from In-Q-Tel remains undisclosed.
Lumen Orbit has rebranded as Starcloud and secured an additional $10M in funding for its space-based data centers, bringing its total seed funding to $21M. The Redmond, Wash.-based startup, which emerged from Y Combinator, plans to launch a 60-kg demonstrator satellite with NVIDIA GPUs on a SpaceX Falcon 9 rocket. The funding will support the development of megawatt-scale computer servers in orbit, reducing the need for terrestrial data centers.
